Well some progress has been made. I've ordered Low Band DXing to obtain the Complete software CD so I can be a bit more efficient in my modeling efforts. I did complete my own spreadsheet to compute

Hi Don: At this point I am not trying to equate simulation with real world performance. Since I am not in the actual building phase just yet, the Only thing I am trying to accomplish is to understand

Hi Terry: I didn't go much beyond the simple LC matching that just jumped out at me when I saw the plot from the attached EZNEC file. I can't absolutely say that I can get this pattern from a real wo
